Bangladesh (/ˌbæŋɡləˈdɛʃ, ˌbɑːŋ-/; Bengali: বাংলাদেশ Bangladesh [ˈbaŋladeʃ] (About this soundlisten), lit. "The country of Bengal"), officially the People's Republic of Bangladesh (গণপ্রজাতন্ত্রী বাংলাদেশ Gônoprojatontri Bangladesh), is a country in South Asia. While it is the 92nd-largest country, spanning 147,570 square kilometres (56,980 sq mi), it is the world's 8th-most populous country with a population nearing 163 million, making it one of the most densely populated countries in the world. Bangladesh shares land borders with India to the west, north and the east and Myanmar to the east, whereas the Bay of Bengal lies to its south. Dhaka, its capital and largest city, is also the economic, political and the cultural hub of the country. Chittagong, the largest sea port, is the second largest city. The country's geography is dominated by the Ganges delta which empties into the Bay of Bengal the combined waters of several river systems, including those of the Brahmaputra and the Ganges. As a result, the country is criss-crossed by numerous rivers and inland water ways. Highlands with evergreen forests cover the landscape in the northeastern and southeastern regions of the country. The country also features the longest natural sea beach and most of the largest mangrove forest in the world. The country's biodiversity includes a vast array of plants and wildlife, including the endangered Bengal tiger, the national animal.
